Video servers must use large disk arrays to provide the huge amount of storage capacity and bandwidth needed. As the number of disk drives increases, the probability of a video server failure increases too. We propose a redundancy scheme that uses both RAID 5 techniques and mirroring to make a video server tolerant against all single disk fail-ures. Our approach provides a unified framework for the use of RAID 5 and mirroring to achieve fault tolerance at the lowest additional cost possible, while guaranteeing 100% service availability even when operating with a failed disk.
